DRUM FOR TURNlNG-LATHES.

QPECIEICATION forming part of Letters Patent No. 357,453, dated February 8, 1887.

Application filed August 13, 1886. Serial No. 210,817. (No model.)

.To all whom it may concern:

Be it known that I, GEORGE BRENNER, a citizen of the United States, residingat Cleveland, in the county of Ouyahoga and State of Ohio, have invented certainnew and useful Improvements in Drums for Turning Lathes; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to a drum or head for holding balusters, spindles, table-legs, moldings, &c., for square turning, the object of the invention being to providea device of this character which shall be simple in its construction, effective in its operation, and in which the. articles to be,turned may be read ily placed without removing the heads of the drum.

With the above and other objects in view, the invention consists in the improved construction and combinations of parts hereinafter fully described, and pointed out in the claims.

In the drawings, Figure 1 is a perspective View of aturning drum or head embodying my invention. Fig. 2 is a longitudinal vertical section. Fig. 3 is a vertical transverse section, and Figs. 4 and 5 are detail views of parts detached.

Corresponding parts in the several figures are denoted by the same letters of reference.

Referring to the drawings, A represents a threaded rod, at one end of which is provided an annular shoulder, a.

13 represents a head, which is fitted on the threaded rod A, and which bears against the inner side of the annular shoulder a, and secured thereto in any suitable manner. The head B is provided with an inwardly-extending circumferential flange, b, and secured in recesses 0, adjacent to the center of the head, and on the inner side thereof are flat springs d, the outer ends of which are free. The threaded rod A is provided with a longitudinal groove or channel, 0, and fitting on said threaded rod is a plate, D, which is received within the head B. This plate D has a central opening to receive the threaded rod A, and

surrounding said opening is a collar, d, preferably rigid with the plate.

Projecting into the central opening of the plate D is a feather or spline, e, which is adapted to engage the groove or channel 0 on the threaded rod A,thus preventing said plate from turning, it being held in place upon the rod against longitudinal movement by means of anut, j, which engages the threaded rod A, and which, when screwed up tight, bears against the collar d.

Upon the outer side of the plate D are se= cured, near the center thereof, flat springs similar to those already described on the head, and when said plate is in position its springs are located between those of the head. The nutfisleft loose enough to allow a slight movement of the head, which, however, is held in engagement with the nut by the flat springs. Upon the other end of the threaded rod is provided a head and plate similar in construction to those already described; but in this case they are removable, being held in place upon the rod by a nut, g.

In operation the squares, strips, or pieces of material to be turned are placed with their ends resting on the inner faces of the heads, the fiat springs being compressed and the plates forced against the heads,thus confining the strips. The inward movement ofthe strips is prevented by circular ledges located ashort distance from the peripheral edges of the plates, and against which the inner edges or faces of the strips being operated upon bear.

It will be seen that by providing the springheld plates strips of different lengths may be placed in the drum for turning, and that it is unnecessary to remove the heads or plates for their insertion in the drum. When the strips have been turned on one side they are removed, and their other sides turned one after the other.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent,'is-

1. The combination,with a rod, of heads arranged at the ends thereof and spring-actuated plates located on said rod, the springs being disposed between the relative heads and plates, as set forth.

ing flat springs secured to their inner faces and plates located on the rod and adjustable 5 with relation to the heads, said plates having flat springs secured to their outer faces and acting against the inner face of the heads, as set forth.

In testimony whereof I affix my signature in 20 presence of two witnesses.

GEORGE BRENNER.
